Stade Francais ace goal-kicker Diego Dominguez is hoping it will be lucky 13 for the French side when they host London Wasps in Paris on Saturday in the second leg of their PARKER PEN CHALLENGE CUP quarter-final.

At stake is a semi-final clash with either Pontypridd or Connacht and it was Dominguez' 81^st minute dropped goal at Adams Park which gave his side a lifeline in the second leg.

The kick clawed the deficit back from three scores to two, leaving Stade to make up 13 points and three tries from a 35-22 deficit.

"We are going to try and win by more than 13 points. The way we do it doesn't really matter just as long as we do it," said Dominquez.

"Both teams respect each other and it will be a mental battle more than anything else. It's going to be very hard and very draining.

"We are going to be putting all our efforts into the game, we really want to do well in this competition."

The icy weather of last week and the rain have left the Stade Jean Bouin ground very heavy and Dominguez believes that will suit the forwards.
